Swift - Building a custom framework

A quick tutorial for building and importing a custom SDK to your project.

save it for a rainy day...

Ceating a Framework:

1. Create a framework in Xcode :? File -> New… -> Framework
2. Uncheck “include tests”?
3. Add code to your framework (a public class \ struct)
4. Build (otherwise the new code won’t compile and be part of the framework!)

Create a workspace in your project:

1. Open a new\existing project you want to import the framework to.
2. Import the Framework to your project by drag-dropping the framework’s .xcodeproj file. This will pop-up a question: “do you want to save this project in a new workspace”?? →?
3. Create a .xcworkspace file by Selecting “Save”.
4. save it in the root folder next to the project’s .xcodeproj file.
5. You’ll see that the workspace is colored in red - that’s because you need to open the xcworkspace file.
6. Open the .xcworkspace file

Add Framework to the Project

1. Go to the general settings of the app’s target
2. Under “Frameworks, Libraries, and Embedded Content” section, hit the + button and Add your framework.
3. If you don’t see the framework in the tree-list, add it with Add Files… drop down menu choose the .xcodeproj file. This will add a group named Frameworks in your file inspector, and Do again the previous instruction (#2)

Quick Reminder - Access modifiers

private - declarations are accessible only within the defined class or struct

fileprivate - declarations are accessible only within the current swift file

Internal - declarations are accessible only within the defined module (default)

public - declarations are accessible by other parts of code but cannot be subclassed

open - declarations marked as open can be subclassed and overridden respectively out of their defining module.
